Can not change Deferred Deletion for ADSAccount table.

Which account is being used to login to Designer?

viadmin. Actually I can change deferred deletion for Person - UNSAccountB etc. that field looks like disable only for ADSAccount table...

What version are you using? Do you have a deferred deletion script set?

9.2. what do you mean deferred deletion script set? How can I check it?  

Your screenshot has a textbox directly underneath your deferred deletion setting. It is called "Script (deferred deletion).

Yes , I know. But I have never used this script section before. I have always set it up from Deferred deletion configuration. So how script side was enabled and configuration side was disabled, I don't know. How can I use the default configuration? Or should I go on with the script?

Btw, version may be 9.2.1.  Is this a new behavior of produt for ADSAccount deferred deletion?

Maybe, right click over text 'Deferred deletion [days]' and see if it says: Permit modification
If so select this and 'Commit to Database' and check for other column locks: select * from QBMLock

The deferred deletion scripts have been introduced with version 8.2, so nothing new. It is optional to use if you need a more fine-grained approach to define the retention time for a table.

I just wondered if a defined script might be the reason for the integer value to be read-only.

OMG guys.... That wasn't be to much easy

I clicked right click then give permit modification. Sometimes if the solution is so easy , you are searching the issue in irrelevant places

Thank you.
